I don't think VB6 can create XLL files. Only ActiveX DLLs which are
different to standard DLLs.

The terminology and acronyms actually confuse me. Nowadays external Excel
libraries are through COM.

Hi,

I have several financial models(monte carlo) created in VB5 which I
use in Excel through dll's(Well Xll's). I use this technique because
my main concern is performance. Would I obtain a siginificant
performance increase if I upgraded my models/functions to a newer
version or platform, say VB6 or higher, VC++ etc? If so, is the
process to create the dll's is as simple as with VB5?
I also own visual studio.Net although I am just learning the ropes.

Specs

Windows Xp
Excel 2000
P4 2 ggz 512 ram
VB5 Pro edition

any help deeply appreciated, thx
